posed throughout the mass of filing elements or records. vThese guidesare usually provided with-tabs to identify and index the various records. In most of the guides used prior to this invention the tabs were affixed to the body of the .guide by an adhesive, rivets or other means. This produced a guide which had several disadvantages. Due to the method of attaching the index tab to the guide body an increased thickness was abruptly produced at a portion of the surface of the guide which came in contact with the iiled records, whereby the entire le wasl caused to assume a fan-like shape, that is, it was wider at the top than at the bottom. It was thusimpossible to obtain an equal pressure over the entire surface of the filed records to iron the same when not in use. This unequal pressure would cause a wrinkling of the typed data thereon and possible obliteration or-smudging of the iiled matter adjacent the abrupt change in the le guide surface. v

I have found that I can eliminate the above described disadvantages by forming or providing an index tab on a record guide which terminates at its lower edge above the upper edge of the body member of the guide whereby when in use it lies outside the general outline of said guide.

It is, therefore, an object of this invention to provide a record guide having an index tab so constructed that it will not produce a fan-like effect in use.

Another object of this invention is to provide a'record guide having a double-faced index tab so disposed that it will not engage the records in the filing system.

A specific object of this invention is to provide a record guide comprising a body member having a tab extending therefrom, said tab having a plurality of apertures therein, a clip having a plurality -of projections registermg with said apertures and disposed on said tab and a transparent sheath disposed on said clip and cooperating there- INDEX TAB FOR RECORD GUIDES with to form pockets to receive index cards,

inserts and the like. v

Other objects will appear from the following description, appended claims and accompanying drawings in which:

Figure 1 is a front view of a central por tion of a record guide including the index tab constituting this invention.

Figure 2 is a sectional view taken on lines 2-2 of Figure 1,- showing the insert in position.

Referring to the drawings wherein like reference numerals designate like parts, the reference numeral 1 designates a body member having a projection or tab 2 extending `therefrom. The body member 1 may be made of any desired shape, size or material.

I prefer, however,` to make it rectangular in shape. Various materials may be used for the manufacture of this guide. I prefer to 'make it of metallic material such as aluminum. The tab 2, as above stated, extends from the body 4member 1. In the drawings wherein a central portion of the record guide is illustrated the tab is positioned in the center of the record guide. It is to be understood, however, that it may be positioned wherever desired.

'I he tab 2 is provided with apertures 3 whlch are adapted to receive projections 4 of a clip member 5, whereby said clip melnber is secured or locked to the tab. The cli member 5 is made of a resilient material suc as tin plate, spring steel or the like, formed 1n the shape of an inverted U. For reasons which will become apparent the portion between tlie legs 5 of the clip 5 may be rounded or beaded out as indicated at 6. 4

As previously stated, the clip 5 is provided with projections 4 in one of its legs 5. These projections may be of any desired type. I have found that I can obtain satisfactory results if the projections are made in the form of sprung-back tongues as illustrated.

Disposed on the clip 5 is a U-shaped sheath 7 formed of a colored .or uncolored transparent material such as celluloid or the like. Thispsheath 7 is provided with inturned edges 8 into which the ends of the legs of the clip 5 extend. The legs of the clip and the transparent member cooperate with each other to form pockets 9 adapted to receive the index cards or inserts 9. By making the curved portion 7 of the sheath 7 engage the beaded portion 6 of the clip 5, close tolerances and substantially uniform pockets may be obtained. Itis to be noted that the pockets are formed on both sides of the index tab 2. This permits the reading of the indices from both sides.

As above stated, one of the essential objects of this invention is to provide a record guide with an index tab to eliminate the fan-like effect when used in the filing system. To'attain this object the clip 5 and its cooperating sheath 7 are made to terminate at its lower edge above the edge of the body member indicated by the reference numeral 10. By this arrangement all parts of the index tab when in use lie above the filed records and do not contact therewith, thus permitting the filed records and the record guides to be flush with each other. Besides eliminating the undesirable fan-like effect, the record guides exert an equal pressure on the filed records thus ironing out said records when not in use. Due to the disposition of the index tab above the body member, the tendency to smudge is eliminated.

In use, due to inclining and flexing of the guide, a record may be caught and held between the tab 2 and the sheath 8. To prevent this, means are provided which will deflect the record outwardly when engaged by the record guide adjacent the lower extremity of the tab. This means may comprise various constructions. In the drawings the projections 11 formed by depressing or olfsettln certain portions of the tab illustrate one. gIhese projections are disposed on both sides of the tab in the portion of the tab 2 above the body member l and below the sheath 8. Any desired number may be used. I have obtained satisfactory results with two on each side, those on one side being staggered with respect to those on the other. Instead of the delecting means above described, a strip of material of triangular cross-section having its thin edge adjacent the bodymember and secured to the tab in any suitable manner may be used.

Instead of forming the tongues and apertures in the clip and tab respectively as above described, the tongues or other projections may be formed in the tab and the apertures in the clip. Also, if desired, the ends of the clip may be bent outwardly in a horizontal direction and form a support for the inserts.

The index clip produced as above described is substantially rigidly secured to the tab. Itl

can only be removed by inserting an instrument, such as a knife blade, between the clip and the tab and spreading said clip sufficiently to permit the projecting portionsto release themselves from the apertures.

Since it is obvious thatlvarious modifications may be made in the specific details above described without departing from the nature of the invention, this application is not restricted to said s ecific details except as deiined in the appen ed claims.
